Also, does anyone know if interrupting the cam or crankshaft sensor works on these engines? That is just a signal and doesn't require much of a microswitch to interrupt.

My metro liked the camshaft signal interrupt switch just fine
My saturn liked the crankshaft signal just fine.

On both it kills the injectors and the ignition so no extra fuel squirted, and no "dieseling" on any fuel remnants. It's the cleanest and quickest, once you figure out how to trick the computer into shutting off the injectors and ignition. Neither one throws any "codes", so I wondered if any honda folks have experimented with this approach.

I made sure they were both turning off by watching an inductive timing light and the gph reading on the guino while playing with the signal leads.

There are ways to kill both injection and ignition with a couple relays, but that may be complicating things.
